Re: Where to get ORIGINAL Anderson Powerpoles for someone outside America

Contact Anderson and ask who their authorized distributors are on your continent, in your country many of their designs are now patent expired so there will be decent quality knockoffs buy original contacts by the 100's, then test other housings? try Mouser Digi-Key Allied Newark Edit https://www.a...

Where to get ORIGINAL Anderson Powerpoles for someone outside America

Hi, I am running out of andersons soon. I used to buy them at Grin along with my orders, but just to ship an order with those connectors would be extremely expensive. There are some online shops, based in the USA, that sell original andersons too, like https://powerwerx.com/ but they also ask for ri...

Re: looking for the simplest balancing circuit

And speaking of surface voltages, a zener diode could be perfect to bleed out any excess voltage above a certain threshold, but due to their "knee" point behaviour it's not practical. Are there more expensive zener diodes which are have a sharper knee point? 24 of these (for my 24S battery) and I n...

Re: looking for the simplest balancing circuit

Sorry but it is most definitely **not** a problem IRL. I was quoting the word "problem", as a joke. Of course this is an advantage. It makes measuring %SOC by voltage only a harder task within the 30%-90% spectrum, that is all. Of course you can choose to top balance because you are most concerned ...

Re: Any lipo checker that is not powered only from first cell?

And what about this unit?
https://www.aliexpress.com/item/4000052302952.html

It's supposed to be also a balancer (albeit only at 50mA), but it's enough to assume that it doesn't drain only the first cell, right?
And it measures from 0V-5V, according to the seller. (I asked)

Re: looking for the simplest balancing circuit

Theres a new style of balancer I've been seeing on youtube, and I think they are called active balancers. When the bulk charge is complete to 4.1V per cell (give or take), the circuit then feeds the highest cell voltage to the lowest cell voltage. If all the cells are within 0.02V (or whatever the ...

Re: looking for the simplest balancing circuit

I don't take LFP CV past 3.45Vpc, any higher is no point as you say no useful energy stored there. Resting 3.33-3.35Vpc is Full. Also as stated the balancing point can be at midpoint, or bottom, no reason to balance at the top, many reasons not to. Nothing to do with any advances true for nearly a ...

Re: Real-time cells voltage display instead of BMS

Since you know your pack well and just want to be able to know when that first cell falls off the cliff at 3V, and you run an even number of series cells, have you considered just running 2 voltmeters (one for each half of the pack)? Then when the 2 voltages become different, you'll know a cell is ...

Hi, I have a 24S A123 battery I have built myself, by using the common screw metal tabs with M5 screws for fastening. I attach a picture of a battery during assembly so you can see what I mean.

I already have a big handle-bar bag which is secured firmly and I have plenty of surface area on it to mount any voltage grid matrix...

I have two of the newer Phaserunner L10's, purchased in August and September 2019. They both transition to plug braking at low speed, consuming power to bring the bike to a complete stop, as their default behavior. The transition from regen to plug braking is quite obvious and a bit jarring (the br...

Hi, I understand that newer versions of the PR, come without plug-braking. That is - regen intensity diminishes as you approach zero speed, but at no point a positive current will be drawn from the battery in order to provide that negative torque. Plug-braking cannot be disabled via the software sui...
